This invention relates to attachments for rifles, and pertains particularlyto an attachment for a bolt action rifle. y

The primary object of the present inven tion is to provide an attachment for a bolt action magazine rifle whereby the same may be operated inthe same manner as a pump gun.

Another object of the invention is to provide an attachment for bolt action magazine rifles which may be employed in connection with either the lift up or the straight slide type of bolt so that the user of the rifie may reciprocate the bolt for the removal of a Vshell and the insertion of a fresh cartridge A sa:

`without taking vthe rifle from his shoulder, the `same as if the ride were of the pump type. -Still "another object of theinvention is to provide an attachment of the above described character for bolt action magazine rides, which may be applied without making any material alteration of the rifle structure. Theinvention will be best understood from a consideration of the following detailed description taken in connection with the accomam:but maybe changed or modified so long as' such changes or modifications markno material departure from the salient features of the invention asexpressed inthe appended claims. y

Figure 5 is a detailed sectional view panying drawings forming part of this speci- Figure 2 is a bottomrplankview of the rifle Figure 7 is an underside-view of the structure shown in Figure 6. Figure 8 isa sectional view taken line 8 8 of Figure 6.

Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views7 the numeral l indicates a bolt action magazine rifle wherein the barrel is indicated by the numeral 2, the forestock by the numeral 8 and the breech and bolt by the numerals 4 and 5 respectively. y

The ride as shown is of the type employing a lift up bolt, this bolt having `an arm 6 which, when shifted forwardly into the breech, is turned down into the recess 7 by which it is held in place.

Itis, of course7 well known that in the usual bolt action type of rifle, whether the same be of the magazine type or of the single shot type, the operator after firing the piece must lower it from his shoulder so that he may conveniently take a hold upon the bolt arm or lever 6 in order to lift it up and pull it back to effect the extraction of the shell and to permit a new charge to be shot into position after which the bolt is shoved forwardly and the lever turned down intothe recess 7 which is formed in the breech for its reception.

With the device embodying the present invention the necessity for taking the gun away from the shoulder and lowering it in order to manipulate the bolt is done away with. This device comprises a hand hold or grip 8 which, as shown, is in the form of a longitudinally split or open cylinder. rlhis grip receives the forestock 3 of the rifle and as the` majority of rifles have the side faces of the forestock provided with longitudinally extending recesses or grooves 9 into which the linger tips of the user are engaged, the

on the f longitudinal edges of the grip may position in forward end of which is formed to provide the eye 12 whichis securedto the rifle forestock 3 by the screw 13 by any other suitable means.

The forward end of theV rod runs longi- V tudinally of the under face of the forestock vll) of the riiie while adjacent its rear end is bent as indicated at 14 so that a substantial por-r is an arcuate link 18 which is formed of a Vsuitable springy or vsemi-stiff material :and

terminates in a hook19 which engages over the bolt lever 6 from which it is prevented from disengaging by the khead thereof which ,Y forms the usual partof this lever.

The pivot v17Vis covered by an extended portion 17 ofthe rod 10 to which it is attached sothat the upward-swinging movement of the link is limited. rlhe guide 16 is so positioned that. when the sliding hand grip 8 is shifted forwardly the end of the link 18 which is attached to the rod 10 will be drawn thereinto so that if the link has been swung upwardly upon the pivot 17, which is disposed at right angles to the path of movement of the' rod and the bolt, when the end of the link is drawn into the guide, it will come intoengagement with 'the rear edge thereof and downward pressure will be exerted thereon tending to swing it down from its raised position.

From the foregoing description it is believed that it will be clear that when the bolt is in position in the breech of the rifle for the ring thereof, by drawing rearwardly upon the hand grip 8 pressure will bepapplied to the spring link 18 which,` being resisted by the locking bolt lever, will cause the link to'be bent or flexed so that an upward` pressure will be exerted thereby upon the bolt lever. This will lift the lever out of the recess 7 and thus permit the boltto besho-ved rearwardly by the continued application of `force to the rod 10. Upon reversely shifting the rod 10 the bolt will be drawn into the breech until the lever 6 strikes the forward edge of the recess, whereupon the lower end of the link 18 will have passed into the guide 16 and, Adue to its curvature and its upwardly Vswung' position, the guide Vwill apply pressure Y thereto so that it will be drawn downwardly 1 and will thus draw the' boltlever down into the recess in which it positions to locate the bolt in place.

In Figures 6 to 8 there is shown 'a modification of my invention for use upon rifles having a bolt of the rectilineal or straight slide type. A. portion of a rifle having a bolt of this'character is shown and indicated generally by the numeral 20, the forestock of which is indicated by the numeral 21, while the breech, the bolt and the bolt lever are indicated by the numerals 22, 23 and24. The hand grip 25 is of the same construction as the hand grip 8 and has securedto the inner face thereof one end of an operating rod 26, Y

the forward end of which receives the supporting rod 27 which is secured to' the forestock of the rifle as lindicated at 28.

rlihe forward end of the rod 26 is disposed 'longitudinally beneath the underside of the forestock and suitable bends are made therein as indicated'at 29"and 30 to position the intermediate portion 31 of the rod lalong the side of the forestock and position a portion vof the `rear end inY spaced parallel relation with the side of the forestockadjacent the bolt 23, as indicated at 32.` The offset rear end portion 32 of the rod26 is suitably secured to the bolt lever 24 as, for example, it may be 'screw threaded to receive the holding nuts 33which, after passing the end l of the rod through an aperture formed in the bolt lever, may be drawn up against opposite faces vof the lever to securely connect the rod and lever together.

In order to indicate to the user of'the'rie when the bolt is in the proper position for firing and also in order to hold the bolt and operating mechanism therefor againstmovement there is securedto the side of the forestock, a strapspring 311.,Y The forward end only .of this spring is secured against move- Y mentv as indicated at 35, whilethe rear end is bifurcated, as at 36, to slidably receive, the

shank of a screw 37, thehead of whichV over- Y lies the furcations to prevent this end of the spring moving away from the stock of the gun. vlntermediate its ends the springs 34:` is bent so that it is substantially V-shaped and stands away from the forest-ock out of contacttherewith except at its'ends, and at the forward side of the bend the spring is provided with. a transverse notch v38.

The bolt actuating rod 26 carries a pin 39 which, in moving the bolt forwardly to posi- Y tion in the breech of the gun, rides up onto the rear end of the spring 34, passing over the bend thereof Aand finallypositioning in the transverse notch 38 when the bolt has reached'its seat.

ln order to make' itpossible to operate the bolts of the rifles shown, the handgrip portion 39. of the stock must be slightly cut away as indicated at 30 so `that the bolt will pass over thev thumb `of theuser of the gun. 1n order to make the gripk of the user more effective the yportion 39 of.l the stock may have added thereto the ,inclined hand grip 41 whichthus gives a pistol grip to the stock.

` ln connection with'the form of the present j invention illustrated in Figures 1 and 2, theer is lshown a device 4:2 which may be used -to support the, rod 15 whenfit is moved rearwardly. yThis device is in the form of aV bracket having a vertical portion which is secured to the side of the gun stock and a `lateral portion over which the rod slides,

readily apparentthat with an attachment of the character herein described upon a bolt action magazine rifle, the rifle is transformed into a pump gun and the bolt may be freely operated without removing the rifle from the shoulder. A
